A recent Cochrane Systematic review of the evidence in treating this injury (Handoll and Vaghela, 2005) found that there is insufficient evidence in existing randomised controlled trials to establish the effectiveness of different (either custom-made or off-the-shelf) finger splints for treating mallet finger injury. They commented that there were only 4 trials that met the inclusion criteria, and all of these were “small, heterogeneous, inadequately described and reported….and had methodological flaws”. Evidence provided is therefore an inadequate base for clinical decision making.
